Question

I write a function such as follows to create a CGPath:

+(CGPathRef)CGPathCreateRoundrect:(CGRect)rect radius:(CGFloat)radius {
    CGMutablePathRef path = CGPathCreateMutable();
    ......
    CGPathCloseSubpath(path);
    return path;
}

The analyzer says the first line of code create a object that is potentially leaked. But i do want to create a new object in this function and transfer ownership to the caller. And the function name contains the key word “Create”. Is this a bug of “Analyzer”?

Answer 1

This is happening because according to compiler understanding a +() method will always return autoreleased variable which is not in your case.
